Hello,
Hello, I'm an expert on these technologies and co-author of Spring Dynamic Modules in action for Manning (2010). I used to work on GWT for 2 years since the first release of GWT alone or with another framework such GXT, GWT Widgets, Gwt-Ext and SmartGWT. If you're interested, I can show you example of my work on such technologies.
I would be pleased to work on this project.
